Responding, Manyi said anyone who has a strong case of corruption against Zuma must launch a case with the relevant authorities.
“Anyone with evidence of stealing must please report the matter to the police.”
Some social media users were angered by the request and accused the foundation of being tone-deaf as many people are unemployed.
“Everyone is asked to help. We are asking from those who have means to help,” said Manyi.
Zuma is recovering in a hospital outside the Estcourt Correctional Centre where he is serving a 15 month jail sentence for contempt of a Constitutional Court ruling.
He was sentenced by the apex court in June for refusing to appear and give testimony at the state capture inquiry.
On Monday TimesLIVE reported the National Prosecuting Authority confirmed his medical team failed to meet the deadline to file a report with the court indicating whether Zuma will be fit to stand trial.
The Pietermaritzburg high court gave the former president’s legal team until last Friday to submit a detailed report on his condition.
